I assume it’s mainly first year calculus since the defining characteristic of running is that it’s repeated launching. Since the downward vector of gravity is a constant I’d imagine a foot to same foot distance is sufficient to solve for speed.
And this is just my first thought as a semi-educated layman. I have no doubt the experts who study these things think of and solve for many other factors. I may not be able to reproduce their work but I can judge it plausible.

There surely must be an assumption about leg length, and that the person wasn't just playing some hop-scotch style game with long, slow, bounding strides. I think I'd need quite strong evidence to convince me that ancient humans were as fast as someone with modern nutrition and training. Especially as (unless I'm mistaken) there's no indication that people in hunter gatherer lifestyles today are particularly fast.
